This time the girl was treated and released after the incident. Bleach can cause permanent eye damage.

Miller said the girl refused to identify the boyfriend who attacked her, which could complicate the ability of police to press charges against him. The boy has not yet been apprehended, but Miller said that will happen as soon as he is identified. The case has been referred to the state Office of Children and Family Services.

Earlier this month, a 15-year-old girl was accused of temporarily blinding a 16-year-old Green Tech Charter High School student with bleach that she splashed on him from a soda bottle. The girl was harassing the boy at the Arbor Hill/West Hill branch of the Albany library. After a librarian asked them to leave, the girl warned the boy he was going to “get the bleach” and returned a few minutes later to attack him, the authorities said. She was charged with second-degree assault.

Police also took a bleach-filled bottle from a girl last week. In that case, the girl was carrying but did not spray the bleach during an after-school fight near North Lake and Western avenues.
